If you're replacing the rotors yourself, there are several pretty serious track guys who use cheap, auto parts store blank rotors. Sure, you have to replace them more often, but it is much less expensive. Z1 has lots of reasonably priced options for upgrades. If you are serious about performance, they have lightweight, 2-piece rotors with replacement rotor inserts - but you gotta pay to play.

Depending on your braking habits both on and off the track, you may get much more or much less life out of your rotors than other drivers. If you're not threshold braking a lot, then you should get more life. But a few hardcore track days can really eat them up if you're going balls deep every corner.

Make sure you get some good brake fluid if you haven't already. Motul RBF600 is good, but RBF660 or Torque RT700 are better if you really push your brakes.
